Open Signal, a software application for Windows 10/11 and 64-bit Linux, facilitates the transmission of color pictures, photo files, and text over HF and VHF amateur radio bands. It integrates its own error-corrected OFDM digital picture mode, delivering pixel-exact images in under a minute, with classic analog SSTV across six families: Martin, Scottie, Robot, Wraase, PD, and MMSSTV's MP/MR, featuring automatic VIS mode detection on receive. The application offers four distinct sending methods, including byte-exact JPEG transfer, a hybrid mode utilizing internet for full quality with a short RF link, and its proprietary digital waveform. This self-contained executable eliminates the need for external software like FLDIGI, Hamlib, or virtual audio cables, simplifying setup. It includes a self-filling logbook that integrates with Wavelog/Cloudlog, eQSL, and provides UDP ADIF broadcast. Built-in spotting features include PSK Reporter, DX cluster announcements, and APRS-IS position beacons. The receive-only version is permanently free, while a full license, enabling transmit capabilities and access to the live network, is available for an annual or lifetime fee. The software is actively maintained, unlike EasyPal, which has not seen updates since 2014.

INTERCOM is a freeware application designed for remote control of KENWOOD TMD700/710/V-71 transceivers, as well as other transceivers equipped with UP, DOWN, and PTT commands. Compatible with Windows XP and higher (32 & 64-bit), INTERCOM offers multilingual support in English and French, and can be used on Linux, Ubuntu, or Android platforms via WINE 1.0 or CROSSOVER. The software enables users to send basic commands—such as selecting TX, VFO, memory channels, or power levels—either through manual inputs or over a TCP/IP link. INTERCOM is tailored for SIMPLEX setups, facilitating the interconnection of VHF/UHF repeaters with nearby repeaters. Remote commands are transmitted using DTMF codes, which are decoded by SIMPLEX and forwarded to INTERCOM via TCP/IP. This functionality makes INTERCOM an ideal tool for radio enthusiasts and operators seeking seamless remote management of supported transceivers in simplex configurations.

The Gemini Amplifier Remote Control software operates on Windows 7 and above, facilitating remote management of the Gemini HF-1K and DX-1200 amplifiers. Users connect via Ethernet, configuring the amplifier's IP address through the front panel. The software allows seamless band and antenna selection, saving settings for each band without requiring transmission. Integration with _OmniRig_ from Afreet Software, Inc. enables automatic band adjustments based on the radio's frequency changes. Users can configure serial or virtual serial connections, with tracking options accessible through the ribbon bar. The software supports speech functionality, enhancing accessibility for operators. Firmware updates, such as version 2.5Ee, introduce features like background datalogging and power output control, uploaded via FTP. Version 1.2.0 allows users to offload internal parameter data for support purposes. The firmware upload process requires the amplifier's IP address and port 21, taking approximately 90 seconds. Users are encouraged to upgrade to the latest firmware for improved performance and remote diagnostics.

Version 0.7 of Open Tuner, released on April 27, 2023, marked a significant milestone by introducing proof-of-concept dual tuner functionality for the BATC Minitiouner. This C# client, inspired by Heather Lomond's _Longmynd_ project, aims to leverage both tuners and demodulators within the NIM module, a capability crucial for advanced Digital Amateur Television (DATV) operations on QO-100 and terrestrial links. My own experience with DATV often involves juggling multiple receive paths, so a unified client like this simplifies the workflow considerably. Further enhancing its utility, version 0.9 (February 11, 2024) integrated support for the Raspberry Pico, utilizing Colin (G4EML)'s _PicoTuner_ firmware. This offers a more accessible and cost-effective alternative to the traditional FTDI module, streamlining dual tuner setups with a single USB cable. The project's evolution reflects a practical approach to overcoming hardware availability challenges. The software is developed using Visual Studio 2019/2022 and .NET Framework 4.7.2, requiring specific Nuget packages like VLC/Websocket and an ffmpeg folder for full operation. It's an active, community-driven effort, with the source code openly available on GitHub for contributions and bug reporting, embodying the collaborative spirit of amateur radio development.

The WSJT Log Viewer, version 1.0.0.10 as of 2026-08-02, is a freeware Windows application developed by Carsten Groen (OZ9AAR) for analyzing signal strengths from WSJT digital mode contacts. It processes the ALL.TXT log file generated by WSJT-X, extracting and presenting data from decoded TX and RX messages. Initially designed for EME operations on 70cm and 23cm, the software has expanded to include all HF bands, 6m, 4m, 2m, 1.25m, 70cm, 23cm, 24GHz, and 47GHz. Key features include displaying total QSOs, unique callsigns, days with activity, and signals heard, with filtering options by band and completed QSOs. The application also monitors the ALL.TXT file for live updates every two seconds, reflecting new decodes in real-time. Users can view session logs, activity charts showing daily signal counts and decoded signals, and a "Top Partners" tab listing the 25 most frequent contacts. The software provides detailed QSO information, including best received SNR and sent reports, with graphical representations of SNR over time. It supports multiple "My Callsign" entries within a single ALL.TXT file and offers a function to generate a text list of initials worked per band. The program is distributed as a single executable file, requiring no installation, and stores its configuration in a LogViewer.cfg file, allowing for different setups via command-line arguments.

Receiving Digital Amateur Television (DATV) signals requires specialized software to interface with hardware tuners and decode the video stream. The _MiniTioune_ software, developed by F6DZP, serves this purpose, providing a Windows-based application for DVB-S and DVB-S2 reception and analysis. It is designed to work in conjunction with _MiniTiouner_ hardware, enabling hams to monitor DATV transmissions, including those from the QO-100 geostationary satellite. The resource outlines the initial setup process, including connecting the MiniTiouner hardware via a high-quality USB2 mini cable and running diagnostic test software. It details how to configure essential parameters such as symbol rate (SR), FEC rate, and DVB mode for various signal sources, from domestic satellite dishes to local DATV transmitters. Troubleshooting steps for common issues like "no video displayed" are also provided, often pointing to corrupted software filters or incorrect _Auto PID_ settings. Advanced features like the Web monitor for remote signal reporting and integration with _VLC_ media player for more tolerant decoding of non-DVB compliant signals are covered. The document also references a comprehensive user guide by W6HHC for the _MiniTiouner-Express_ system, which utilizes the same software, offering further in-depth assistance for operators.
